NAME

Alien::Build::Plugin::Build::Autoconf - Autoconf plugin for Alien::Build

VERSION

version 2.83

SYNOPSIS

use alienfile;
plugin 'Build::Autoconf';

DESCRIPTION

This plugin provides some tools for building projects that use autoconf. The main thing this provides is a configure helper, documented below and the default build stage, which is:

'%{configure} --disable-shared',
'%{make}',
'%{make} install',

On Windows, this plugin also pulls in the Alien::Build::Plugin::Build::MSYS which is required for autoconf style projects on windows.

The other thing that this plugin does is that it does a double staged DESTDIR install. The author has found this improves the overall reliability of Alien modules that are based on autoconf packages.

This plugin supports out-of-source builds (known in autoconf terms as "VPATH" builds) via the meta property out_of_source.

NOTE: by itself, this plugin is only intended for use on packages that include a configure script. For packages that expect you to use Autotools to generate a configure script before building, you can use Alien::Autotools to generate the configure script and use this plugin to run it. For more details see the documentation for Alien::Autotools.

PROPERTIES

with_pic

Adds --with-pic option when running configure. If supported by your package, it will generate position independent code on platforms that support it. This is required to XS modules, and generally what you want.

autoconf normally ignores options that it does not understand, so it is usually a safe and reasonable default to include it. A small number of projects look like they use autoconf, but are really an autoconf style interface with a different implementation. They may fail if you try to provide it with options such as --with-pic that they do not recognize. Such packages are the rationale for this property.

msys_version

The version of Alien::MSYS required if it is deemed necessary. If Alien::MSYS isn't needed (if running under Unix, or MSYS2, for example) this will do nothing.

config_site

The content for the generated config.site.

HELPERS

configure

%{configure}

The correct incantation to start an autoconf style configure script on your platform. Some reasonable default flags will be provided.

ENVIRONMENT

SITE_CONFIG

For a share install, this plugin needs to alter the behavior of autotools using site.config. It does this by generating a site.config file on the fly, and setting the SITE_CONFIG environment variable. In the event that you already have your own SITE_CONFIG set, that file will be sourced from the generated one, so your local defaults should still be honored, unless it is one that needs to be changed for a share install.

In particular, the lib directory must be overridden, because on some platforms dynamic libraries will otherwise be placed in directories that Alien::Build doesn't normally look in. Since the alienized package will be installed in a share directory, and not a system directory, that should be fine.

ALIEN_BUILD_SITE_CONFIG

If defined, this file will be also be sourced in the generated site.config. This allows you to have local defaults for alien share installs only.
